I actually don't understand christians who are against abortion as god carries out so many himself.
Not being a Christian, or of any religious persuasion for that matter, I too must confess to not understanding Christians sometimes as well ... though, with regard to the topic, that's purely irrelevant.
But if you want to play the "God" card, Dawkinsrocks, which, incidentally, is not about religion, then consider ...
... That if God is the one who performs spontaneous abortion, and God is the one who gets people sick from disease, and God is the one who causes accidents, and God is the one who causes deadly disasters and famines and such that take the lives of human beings, ...
... Then why do we cringe when dictators in Africa withhold food from their citizens, starving them to death ...
... And why do we find terrorist-created disasters that kill people so revolting ...
... And why do we become incensed when a killer sets up an accident scenario that snares his intended victim ...
... And why do we become outraged when someone is spreading the deadly disease of anthrax in the mail to people ...
... Why, Dawkinsrocks?
The answer is because we get that it is
wrong for people to kill people, even if there are times that it might be God who does kill people.
That's why people become outraged at murderous abortion, Dawkinsrocks: because it's simply
wrong for people to murder people.
What God might do is God's business, God being who he is by definition.
But, though religion is irrelevant, even the major three social religions portray God as ordering us not to kill each other in "thou shalt not kill" manner, so if you want to try to understand Christians who oppose abortion, maybe that will help you.
But for the overwhelming vast majority, whether they're religious or not, their sense of outrage over people killing people is a natural
human reaction, void of any need for outside "A"uthority validation.
That's really all there is to it.
But in answer to your question, rights accrue in accordance with circumstances.
For example, animals have the right to be treated decently but they don't have the right to a fair trial.
Sometimes rights clash and a hierarchy evolves.
A few brainless cells do not have any rights.
A woman does.
And the constant personification of the foetus is evidence of the weakness of the 'pro life' lobby's argument.
It is not a baby, a child or a person.
They have accrued rights.
You error in your understanding of what rights are, Dawkinsrocks, as well as in your understanding of what a person, a unique individual human being, is.
Please refer to:
The Realities of Rights.
That should explain to you what rights are.
Once you grasp that, ...
... And you accept science's declaration that, no matter how many cells that person consists of, that person, a unique individual human being, is so from the moment of conception ...
... Then when you couple the scientific fact with the realities of rights, perhaps then you'll have sufficient information and knowledge to correctly conclude that non-life-or-death-self-defense abortion is killing that is sociologically described as murder.
People just don't like murder, Dawkinsrocks -- they hate and fear murder, and that's a natural healthy human response to murder, no matter who's being murdered and no matter who's doing the murdering.
I'm sure you understand that, don't you?!
